Problems solved by technology

Natural antibacterial agents have good safety to the human body and are a type of environmentally friendly antibacterial agents. However, due to their poor washability, most of them affect the shade of fabrics and the processing conditions are high, so the application range is narrow
The types of organic antibacterial agents include aldehydes, phenols, alcohols, quaternary salts, organic metals, and organic nitrogen. Due to poor chemical stability and thermal stability, short life, easy oozing, poor washability, and certain toxicity and volatility, it can cause irritation to eyes and skin, thus limiting its application in the field of antibacterial

Abstract

The invention discloses a finishing method for a textile with ultraviolet-resisting and antibacterial functions. The finishing method comprises the following steps: step (10), preparing a zinc oxide / carboxymethyl chitosan nano compound; step (20), pre-treating the textile with a cold plasma method; and step (30), preparing the zinc oxide / carboxymethyl chitosan nano compound prepared by the step (10) into a zinc oxide / carboxymethyl chitosan nano compound solution, and immersing the textile pre-treated by the step (20) with the solution; and adding an acrylic ester binding agent and adopting a rolling baking process to obtain the treated textile. The textile prepared by the finishing method has good ultraviolet-resisting and antibacterial functions.

Description

technical field [0001] The invention belongs to the technical field of textile materials, and in particular relates to a method for finishing textiles with anti-ultraviolet and antibacterial functions. Background technique [0002] The environmental pollution brought by industrial development has led to a reduction in the concentration of the ozone layer, and the ultraviolet rays radiated to the ground from the sun have increased accordingly, and the impact on humans has increased significantly. People began to pay attention to their own protection, and anti-ultraviolet textiles, like other protective products, have received people's attention. Anti-ultraviolet finishing agents at home and abroad are generally made of one or more ultraviolet absorbers, shielding agents and other substances as raw materials, and are formulated after adding appropriate auxiliaries and related additives. General organic anti-ultraviolet substances are stable to a certain extent, but long-term ...
